Answer:
a computer receives signal
They provide wind energy
Wind power consists of turning energy from the wind to other energy forms.
Windmills have been in use since 2000 B.C.
developed in Persia
Wind energy is the fastest growing mode of electricity
Wind farms can be constructed in off shore locations
Wind energy is renewable and pollution free source of energy
Most of the modern wind turbines have 3 blades
The largest wind turbine in the world is located in US in Hawaii
The first modern wind turbine was built in 1940’s in Vermont.
Answer:
computer file is a computer resource for recording data discretely in a computer storage device. Just as words can be written to paper, so can information be written to a computer file. Files can be edited and transferred through the internet on that particular computer system.
Answer:
The output of code will be 10
Explanation:
We need to find output of following code:
C = 1
Sum = 0
while (c less than 10):
C = c + 3
sum = sum + c
print (sum)
Solution:
We will check the condition of while loop, if the condition is true, then the statements inside the loop will be executed. Since brackets are not available so, only one statement is linked with while loop.
First while loop will be executed c < 10 (1<10) the condition becomes true, and statement c=c+3 will be executed ( 4=1+3) and then loop condition will be checked (4<10) the condition becomes true, and statement c=c+3 will be executed ( 7=4+3) and then loop condition will be checked (7<10) the condition becomes true and statement c=c+3 will be executed ( 10=7+3) and then loop condition will be checked (10<10) the condition becomes false, so we will come outside loop body and execute: sum=sum+c (10=0+10) and print sum i. e 10
So, The output of code will be 10
Answer:
1.48 s
Explanation:
Number of instructions = 500 million = 500 * 10⁶
clock rate = 1 / 2.2 GHz = 1 / (2.2 * 10⁹ Hz) = 0.4545 * 10⁻⁹ s
We need to compute the clocks per instruction (CPI)
The CPI = summation of (value * frequency)
CPI = (50% * 3 clock cycles) + (50% * 10 clock cycles)
CPI = (0.5 * 3) + (0.5 * 10) = 1.5 + 5 = 6.5
Execution time = number of instructions * CPI * clock rate
Execution time = 500 * 10⁶ * 6.5 * 0.4545 * 10⁻⁹ =1.48 s
